IMPROVE!) SIERING-BED BOTTOM.

The Schedule referred to in these LettersfPatent and making part of tlxesame.

To all whom it may concern Be it known that I', JOSEPH MOORE, of Tarentum, in the county of Allegheny, and State of Pennsylvania,

have invented a new and improved Spring-Bed Bot` `na1 spring-bars upon transverse bars, one near each end, which are suspended by spring-followers, enclosed in suitable cases, in the said cross-bars, and connected by straps to the frame ofthe bedstead, in such a way that the followers work out and in, in connection with vlon elastic springs as theA pressure varies, all as herein r more fully specied.

Figure 1 represents a transverse section of my improved spring-bed flame, taken through ,one of the transverse supporting-bars, and y Figure 2 represents a longitudinal section of' the same.

Similar letters of reference indicate corresponding parts. y

A represents the common longitudinal slats; and B, the transverse supporting-bars. y

These are provided with spring-followers C, en-

closed in a case, D, andl connected to straps E, snspended by hooks to the frame of the bed, and working under friction-rollers F, at the ends of the barsfB.

Tige saidrfollowers are provided with long spiral springs G, which may'V have any amount of play or movement, and thus be more elastic and flexible than when made shelter, or arranged in positions necessa-v rily confined, The said springs are contracted underthe weight of the load, and expanded when the load is removed.'

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The combination of the longitudinal spring-bars A,

transversel bars B, spring-followers C, straps E, and

friction-rollers F, substantially as specified.

JOSEPH MOORE.
